The ICRF-3 proposal to the 2018 IAU General assembly improves the precision, spatial coverage, and frequency coverage relative to the current standard, the ICRF-2 (Ma et al, 2009).This paper will discuss all three frequencies (8, 24, 32 GHz) of the proposed ICRF-3 highlighting their strengths and weaknesses. Inter-comparisons will be used to estimate true accuracy of the frame. Comparisons of radio-based VLBI frames to the optical Gaia DR2 frame will provide a complementary assessment from an independent wavelength and technique. We will close with prospects for future development of the ICRF.< Leer menos
